Helping a friend swap out tabs. One hinge pin seems to be frozen in the backing plate, therfore not allowing for the tab to be removed. Other side slide out with little trouble.

No visable corrosion anywhere. Have soaked the pin at all points where it goes thru the backing plate with several kinds of lubricant. No luck. Done it for several days.

Have tried and air hammer, and a small sledge. The pin wont budge or turn at all.

I used the search function here and got little results.

Any idea's past trying to cut the hing pin at several points to get the tab off, then try to get the individual pieces out of the backing plate hinges ?

The tab its-self pivots freely, the pin itsself wont budge or turn so we can slide the pin out to get the tab off.

I'm afraid you will not get it out as a whole pin if you haven't already.

I bee through this a few times and what happens is the corrosion inside is like powder and just binds with everything else in there.

Heard of plenty of people using a torch.
I'm not fond of this because you change the strength properties of what is already a cast aluminum part.
also you trash the paint.

Personally i have cut three different set's of trim tabs
between each joint with a saw zaw.

Then you can use a punch and get each piece out pretty easy at that point.

I have always made my own pins,.....
Order stock from McMaster Carr

Drill and Tap the ends in a lathe, or turn the ends in the
lathe for a stainless c-clip.


Don't for get to chase the holes with a flapper wheel or
a drill and get the corrosion out after you pin is removed.


Good Luck

I went through the same thing last year. I cut the pin so I could remove the bottom plate then I drilled out the pin. I started with and 1/8" bit and worked my way up. Was a tedious job, but I got the pin out. Use lots of wd-40 or cutting oil when you are drilling. I went through a few drill bits! Good luck

Thanks for the input. Didnt think a sawzall blade could get in there, but havent tried it either. Sounds like a ***** any way you go. Not fond of the torch route either.
